Definitions

  • the invention relates to a device for removing excess process air from a chamber delimited by concave wall sections for generating a fluidized bed flow of a tobacco / air mixture moving along the chamber wall in order to form a tobacco rod made up into a rod of smoking articles.
  • Devices of the type mentioned above are usually used in machines in the tobacco processing industry where blown air is used to support or reinforce a tobacco-promoting or accelerating component, the excess of which has to be removed again from a quasi-closed system, such as the cigarette machine distributor.
  • the invention has for its object a largely to create trouble-free and maintenance-free air circulation system of a tobacco processing rod machine.
  • this object is achieved by a stationary air extraction system installed essentially in the area of the chamber center.
  • fine particles or dust components of the tobacco flow which are subject to the centrifugal force, are held on the concave chamber wall and, if necessary, guided around until they are included in the strand structure.
  • the excess process air drawn off centrally remains unaffected by such dust components.
  • An optimal embodiment consists in that the air suction is designed as a tubular body which has an air inlet on the underside or facing away from the ceiling wall section of the chamber. In this way it is prevented that tobacco falling from the upper chamber wall interferes with the air suction when the strand formation process (so-called strand stopper) is interrupted.
  • the air inlet of the tubular body is expediently equipped with sieve openings. Uniform air extraction over the entire distributor width (perpendicular to the plane of the drawing) is achieved according to a further development in that the air inlet merges into a slit nozzle that narrows towards the tube center.
  • the advantage achieved by the invention is that a clean separation of tobacco or smaller tobacco particles, such as tobacco dust, and conveying air already takes place in the distributor chamber preparing the strand assembly, so that largely dust-free conveying air can be returned to the circulating air system.
  • the lower dust pollution of the exhaust air achieved in this way can be used, for example failure-prone, maintenance-intensive fine dust filters and the like can be dispensed with.
  • the drawing shows a section through part of a distributor of a cigarette rod machine of the type PROTOS, which is widely used and known in the tobacco processing industry.
  • the tobacco supply upstream of the part of the distributor shown and the removal of the tobacco from the tobacco supply are widely known, for example from DE-OS 42 40 459, and do not require any description here.
  • the drawing shows a storage chute 1 with a tobacco supply 2 and a removal device 3, which consists of a rotating removal roller 4 and a faster rotating beater roller 6.
  • the visible air flow separates the light tobacco fibers 8 from the heavier tobacco fibers 9 (tobacco ribs) and transports them transversely in the direction of arrow 16.
  • Some light tobacco fibers 8 sink down with the heavier tobacco ribs 9. You get through a rotary valve 17 into a viewing shaft 18 in which the heavier tobacco ribs 9 sink further down and are discharged, while the lighter tobacco fibers 8 due to the injector effect of a blown air jet a blowing air nozzle 21 arranged in a pressure chamber 19 rise up and are returned to the stream of light fibers 8.
  • the tobacco fibers in the example shown are transferred to a guideway in the form of a curved guide surface 24 of a distribution chamber 26 delimited by concave wall sections, on which they loosened up a thin stream of tobacco 27 (exaggerated in the drawing) and spread tobacco fibers, with blown air and tobacco fibers forming a wall flow moving closely along the guide surface 24.
  • a blower air nozzle 28 is provided in a pressure chamber 29 and optionally further blower air nozzles arranged in the course of the guide surface 24 and not shown in the drawing are provided.
  • the loosened and spreading tobacco stream 27 arrives in a strand build-up zone 31 to a suction strand conveyor 32, to which a suction draft for forming and holding a tobacco strand 34 is applied from the rear by the suction effect of a vacuum chamber 33, suction air the strand 34 and the air-permeable suction strand conveyor 32 flows through.
  • Excess blown air supplied via said blown air nozzles 14, 21, 22 and 28 escapes via a stationary air suction 36 arranged in the center of the distribution chamber 26.
  • the air suction 36 consists of a tubular body 37 which has an end on its underside or the top wall section of the distribution chamber 26 an air inlet 38 is provided which has sieve openings 39.
  • the air inlet 38 merges into a slit nozzle 41 which narrows towards the inner tube center and extends over the entire width (perpendicular to the plane of the drawing) of the distributor chamber 26.
  • the interior of the tubular body 37 and the vacuum chamber 33 of the suction line conveyor 32 are via air lines 42 and 43 with the suction side and the pressure chambers 13, 19, 23 and 29 via air lines 44 and 46 or 47 and 48 with the pressure side of a not shown Blower connected within a closed air recirculation system.
  • the suction line conveyor 32 which is designed as an air-permeable conveyor belt, runs in a tobacco channel 49 which is laterally delimited by two channel cheeks 51.
  • the end section 52 of the guide surface 24 is aligned with one of the channel cheeks 51, so that a seamless, smooth transition of the guide surface to the tobacco channel 49 is ensured.
  • the end section 52 of the guide surface 24 is designed as a guide body 54 which can be pivoted about a pivot axis 53 in order to ensure better accessibility of the device in the event of faults.
  • the tobacco fibers 8 fed through the channel 11 are deflected by the blown air stream out of the nozzle 14, ribs 9 being separated. Blown air flows from the nozzles 21 and 22 convey the deflected fiber flow, conveying the undeflected light tobacco fibers 8 to the guide surface 24, along which it is conveyed from the nozzle 28 into the tobacco channel 49 and to the suction line conveyor 32 with the aid of the blown air flow.
  • the tobacco fibers are held as rod 34 on the moving suction rod conveyor 32 and conveyed away perpendicular to the plane of the drawing.
  • the tobacco rod is then wrapped in cigarette paper in a rod unit (not shown) of the cigarette rod machine and the latter is glued in an edge area. Cigarettes are then continuously cut from the endless cigarette rod thus formed.
